Be' it known `that I, EUGEN SECKLER, a subject of the Emperorof Germany, residingat VLake View,'in theV county of Passaic, and State of Newdersey, haveinvented certain new and useful Improvements in Comber-Boards, Vof which the following is aV specification.

This invention relates to comber board structures for looms and it has for its principal object to provide a comber board structure which will permit the harness cords to be quickly, and readily adjusted relatively to each other, as in, altering the loom for weaving fabrics varying in width or count of the warp. Y

In the accompanying drawings, Figure l is a front elevation of a' Jacquard machine, the harness cords depending therefrom, a fragment of the batten structure of a loom and two of the improved comber board structures as they are preferablyemployed; F ig; 2 is a plan view of the improved comber board structure;` Figs. 3 and l are a transverse sectional view on the line in Fig. 2 and a fragmentary longitudinal sectional view of the improved comber board; Fig. 5 illustrates a detail; and Fig. 6 is a diagrammatic view illustrative of the adjustment of one of the harness cords.

The holes to guide the harness cords A shown in Figs. l and 6 are formed in the improved comber board structure by two crossed groups of parallel horizontal rods a and Z) (F ig. 2), the groupa being arranged inpractice to extend transversely and the group b approximately longitudinally of the warp.

The rod group .a may be supported as follows: 0 is a suitable elongated rectangular frame including the cross bars d each formed with a rabbet d on the inside. vIn this rabbet there is removably secured', by means of screws e, a strip f which isperforated to receive the end portions of the rods of the` group a, which are kept against undue longitudinal -movement b y abutting against the shoulder formed by the rabbet cl of the cross bar, as shown best in Fig-t.y At a suitable distance apart there are provided the cross strips g penetrated by the rods of the group a and serving to keepsaid rods properly spaced from each other; said` strips also serve as intermediate supportsfor the rods a to keep the latter from sagging, and to this end the strips g rest at their ends on the i S'pecficatin of Letters Patent.

angular bars g which are supported at their ends on the cross-bars d and at the middle by the stirrups g secured to the sides c of the frame. It is preferable that the rods a be staggered, as shown in'Fig. 3. It is obvious that in order to change the number of the rods a or replace them with new ones from time to time it' is only necessary to detach one or the other of the strips f.

For supporting the rod group Z) and providing for the adjustment thereof I preferably employ the following instrumentalities: The long sides c of the frame 0 have inwardly facing longitudinal grooveshon the inside. The inner face of each side o has secured to it two spaced metal strips t partly covering its groove fr. (Fig. 3); The ends of the rods b aire received in the grooves L, extending between the twostrips z' in each instance. For convenience in removing the group apart c of each side c overlying the 'groove 7L may be' detachable, being held in place by screws 0 or otherwise.

j Vdesignates tworseries of wedge-shaped spacers employed for altering theI spacing of the rods b. They are provided with eyes j as shown best in Figs. 3 and 5 and are strung on the two horizontal bars it', which entend` parallel Awith the rods a, their ends being received in vertical slots Z in pairs of brackets m which are suitably secured to the sides c of the frame 0,' the bars 70 are adapted to be vertically' adjusted by the screws n, having` lock `nuts V0 (adapted toy bind against the brackets m), and then held securely by the screws 2), each pair of screws wand y) being tapped at the opposite ends of the slot Z in each bracket. The spacers j are kept' substantially' upright by the sides c of the frame and the rods or wires g arranged in the brackets m parallel with said lsides (Fig. 3).` The spacers altei-nate with the rods b, and it 'will be obvious that upon their vertical adjustment the spacing of the rod group ZJ will be varied, assuming, of course, that the rods and spacers are all held in compact or contacting order. After the adjustment the rods and spacers as an entirety are held against lateral displacement bythe blocks r, each of which is penetrated by a bolt r whose T-shaped head is received in the slot la, and whose nut 1*'coacts with the head when screwed up tight to clamp the block to the strips i. Reserve spacers are shown at the eXtreme right and left on the bars le in Fig.

lOO

2; if more rods Z) were required to be used, a corresponding number of the reserve spacers would be brought between the ltwo The improved comber board is suitably supported in 'a horizontal plane between the Jacquard machine s (Fig. l) and the plane` ofthe hatten structure shown in Fig.'1 as` including the batten proper t and the reed u. By raising or lowering-the bars the spacing of the rods of the comber board will4 be changed to suit the count. of the particular reed u employed, it being understood that after the adjustment is effected the blocks r are employed to hold the group of rods b and spacers coinpactly together and in vertical registry with the warp. It will be seen that the rods Z) may be shifted as a group so as to stand obliquely to the length of the warp, the advantage of which is that the holes which they form for guiding the harness cords will be in front or rear elevationdistributed j vequally over the entire breadth of the cord group thereby to provide a certain clearance for each cord with respect to the others in the same front to rear row which would not eXist if the rows were strictly parallel with the warp threads.

Assuming that the heddles A of the y cords A are leveled, it will be apparent that upon either expanding or contracting the comber board the heddles would cease to be level butkwould arrange themselves in an upward or downward curve (according as the -comber board is expanded or contracted, respectively) this is undesirable, as the warp should stand as nearly as possible in a perfect plane. I have found that if two coinber'boards be employed one abovethe other, one being adapted to be expanded as theV other is contracted, and vice versa, the effect of one upon adjustment to disturb the planiforin arrangement of the heddles may be offset by reversely adjusting the other. Thus, referring to Fig. 6, if the rod I) of the lower coinber board upon adjustment to the dotted line position would effect the elevation of the heddle A to the dotted line posi.- tion, the adjustment of the rod b of the upper combei board in the direction of the arrow in Fig. 6 (reversely to the adjustment of the rodV b of the lower comber board) would accomplish depression of the heddle A.

Having thus fully described my invention, what I claimpas new and desire to secure by Letters Patent is Y 1. In combination, a supporting structure, two crossedv groups. of parallel spaced rods arranged in said structure and together d several rods of said group. c Y Y 2.

Y t, u l' Y 4:. In combination, a supporting-structure, two horizontal crossed groups of parallel spaced rods arranged in said structure and together forming guiding holes for the-harness cords, and means to alter the spacing of one group of said rods including a substantially horizontal bar, a system of wedge-v shaped spacers movable individually on andY in each of said sides, a group of parallel spaced rods having their ends received in said grooves, another group of parallel spaced rods crossing theriirst group and forming therewith guiding holes for the harness cords, the firstV group of rods being movable longitudinallyof said grooves, and

G. In combination, aY supporting structure, two crossed groups of parallelspacedrods arranged in said structure. and together forming guiding holes for the harness cords,

and means to adjust all the rods of one group into and out of right angular disposition to the rods of the other group.

In testimony whereof I amx my signature in presence of two witnesses.
